Lusatia

Lusatia is a region of eastern Germany between the Elbe River valley to the west and the Bobr and Kwisa rivers to the east, along the Oder-Neisse Line. Its name comes from the Sorbian word luzicy, meaning "swamps", and the region is now a part of Germany's Saxony and Brandenburg regions and Poland's Lower Silesian Voivodeship and Lubudz Voivodeship.
